Doesn’t the Bible teach the permanent condition of Hell/Hades?
Paul asks the Romans," Romans 11:22;25;27 Behold therefore the goodness and severity of God: on them which fell, severity; but toward thee, goodness, if thou continue in his goodness: otherwise thou also shalt be cut off.  For I would not, brethren, that ye should be ignorant of this mystery, lest ye should be wise in your own conceits; that blindness in part is happened to Israel, until the fulness of the Gentiles be come in.  For this is my covenant unto them, when I shall take away their sins.”
This has not the slightest reference to the world after death, nor to the fate of mankind in that world. This is demonstrated in a two-fold manner:
1. Death and Hell/Hades will deliver up their occupants. Rev. 20:13.
2. Hell/Hades is to be destroyed. I Cor. 15:55; Rev. 20:14.
Therefore, Hell/Hades is of temporary duration. Whatever the state of either the righteous or the wicked may be, while in Hell/Hades, that state will certainly cease, and be exchanged for another at the general resurrection. Thus the New Testament usage agrees exactly with the Old Testament. Primarily, literally, Hell/Hades is death, the grave, and figuratively, it is destruction. It is in this world, and is to end. The last time it is referred to (Rev. 20:14) as well as in other instances (Hosea 13:14; I Cor. 15:55), its destruction is positively announced. So that the instances (sixty-four) in the Old Testament and (eleven) in the New, in all seventy-five in the Bible, all perfectly agree in representing the word Hell, derived from the Hebrew Sheol and the Greek Hades, as being in this world and of temporary duration.
